This is only a guess but I can see three possible things are happening here...
The exception is very clear, you've created the database (ligas_db) but not a table within it (no such table exception = there is not a table named ligas_db).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
